Hi, I have a friend and she is 24 years of age. She is in UK right now. She was having some health troubles lately. She had blood in her cough. Her X-Rays showed that her lymph nodes were enlarged. Doctors conducted some tests and ruled out TB or any sort of cancer. Yesterday she tested positive for a D dimer test. Doctors say she might have a blood clot in her lungs.She has had episodes of fainting and low blood pressure during our college days. I am really worried. Right now doctors have given her some injection to dilute her blood. My question is that if eventually it turns out to be a clot in her lungs, can she be cured??
